Our Plain ID Tag is golden metal, with a 1/2-inch by 2-inch rectangular plaque. The total length is just over 6 inches. We like to remove the chain (keep it for another project of course!) and use the plaque as a tag on all kinds of artwork.
Or consider using one of these as a gift tag by personalizing it and hanging it over the neck of a bottle of wine. What a special gift.
Alcohol-based inks and dyes work best, but try anything. We've also used metal alphabet punches to indent special messages on the small plaque.
